Correspondence on A Theoretical Investigation of the Failure of Open Sandwich Beams Due to Interfacial Shear Fracture

Professor R. P. Johnson (F) (University of Warwick): It is shown by numerical analysis in this paper that simply supported, open sandwich, steel reinforced concrete beams are not susceptible to failure by propagation of a crack along the adhesive layer. This is consistent with the results of a series of tests published in 1981, in respect of cracks that initiated within the length of the steel plate.
